gpu: nvgpu: add API to extract gk20a pointer from cdev

Browse Source 
Add new API nvgpu_get_gk20a_from_cdev() that extracts gk20a pointer
from cdev pointer. This helps in keeping cdev related implementation
details in ioctl.c and away from other device ioctl files.

Also move struct nvgpu_cdev, nvgpu_class, and nvgpu_cdev_class_priv_data
from os_linux.h to ioctl.h since all of these structures are more IOCTL
related and better to keep them in ioctl specific header.
